Choice-based Valuation of Natural Resources In the Protected Area of the Evros Delta
نویسندگان
چکیده
The paper investigates the economic valuations individuals make about natural resources in the protected area of the Evros river delta in NorthEast Greece. A choice experiment is conducted to quantify in monetary terms the value of natural resources, focusing on four key aspects associated with a healthy local ecosystem, (a) the withdrawal of saline soils, (b) the decrease in the use of nitrates and phosphates, (c) the protection of habitats, and (d) transfer of labor to eco-friendly human activities. We apply choice models to analyze the preference structure of residents for alternative scenarios of ecosystem’s evolution in a ten years horizon. The main focus of the modeling approach is inference about welfare valuations and their relationship with the characteristics of the participants to the choice experiment and their perceptions about the importance of ecosystem services. We derive welfare estimates and detect a number of significant linear and non-linear effects that may inform environmental protection and regional development policies.
